9. How much energy does a 100 W light bulb use in half an hour? If the light bulb converts
yulyashka [42]

The energy used by the light bulb in half an hour is 180000 J and the amount of thermal energy generated is 158400 J.

What is Energy?

Energy is the ability or the capacity to do work.

To calculate the energy of the light bulb we use the formula below

Formula:

  • E = Pt.......... Equation 1

Where:

  • E = Energy used by the bulb in a half-hour
  • P = Power of the bulb
  • t = Time

Given:

  • P = 100 W
  • t = 1/2 hour = 30 minutes = (30×60) = 1800 seconds

Substitute these values into equation 1

  • E = (100×1800)
  • E = 180000 J

  • If the light converts 12% of electric energy to light energy, then  88% of the energy is used to generate thermal energy

Therefore,

  • Thermal energy = (180000×88/100) = 158400 J

Hence, the energy used by the light bulb in half an hour is 180000 J and the amount of thermal energy generated is 158400 J.

Why are the temperatures on each of the other terrestrial planets more extreme than earth?
netineya [11]
Other terrestrial planets have more extreme temperatures mainly because of their atmospheres
Explanation:
for example the atmosphere of Venus is composed mainly of carbon dioxide, this carbon dioxide traps the heat or energy from the sun and makes the planet have higher temperatures. where on mars the atmosphere is very thin so it takes in lots of heat and doesn't keep it in very well so it gets very hot and very cold

What is defined as a special kind of systematic observation, used by correlational researchers,
erica [24]

Longitudinal design is defined as a special kind of systematic observation, implemented by correlational researchers, which involves the tasks of obtaining measures of variables of interest in multiple waves over time.

<u>Explanation: </u>

Longitudinal design is one of the known systematic observation pattern followed by the correlational researchers in which a subject of experiment is observed for a significantly long span.

The three types of longitudinal design are: panel study, cohort study and retrospective study. The complete design involves the multiple set of observations over a variable or subject. Longitudinal design is often used in clinical psychology to study rapid fluctuations in the behaviour.
